In the seventh year of Tang Wude, a rebellion scandal broke out in this new empire. The crown prince Li Jiancheng, worried about the military strength of his second brother Li Shimin the Prince of Qin, took advantage of the opportunity of his father's summer vacation at Renzhi Palace in Yijun County to privately mobilize his forces to send a batch of ordnance to Yang Wengan, the governor of Gyeongju, in the hope of strengthening his military strength.
However, due to the lack of secrecy, the matter had already been sent to the Qin King's Mansion by spies. When Li Shimin learned of the news, he immediately reported to Li Yuan that Crown Prince Jianjian had privately sent ordnance to Yang Wengan, the governor of Gyeongju, with the intention of rebellion.
After hearing about the incident of the prince sending ordnance to himself, Yang Wengan immediately rebelled, which also took Li Jiancheng's position very passively.
According to the reason, even if Li Yuan fell lightly, Li Jiancheng's position as prince should be removed. It is also true that under the blows of the heroic group led by Li Shimin, Li Jiancheng soon became a single-handed force.
However, just as Li Shimin was successful, Emperor Li Yuan pulled a side of the fight and played fifty boards on both sides. As for his son's suspected rebellion, why did Li Yuan have no suspicion, and did he not like Li Shimin?
As we all know, in the circle of founding emperors, Li Yuan was a famous "family squat", basically eliminating the dirty work of separatist forces was done by Li Shimin.
Although this is very worry-free, it also creates a very acute problem, a huge contradiction between the emperor and the meritorious group. This contradiction only appeared in the founding emperor, but because Li Yuan's family was squatting, he did not have a particularly strong suppression of the Gongchen group.
Under such circumstances, it was absolutely impossible for Li Yuan to make Li Shimin the crown prince. If Li Shimin became the crown prince, Li Yuan would be very insecure, because once Prince Li Shimin became annoyed and wanted to become emperor, he would have to step down immediately and have no countervailing power.
Li Yuan's handling of the Yang Wengan incident made Li Shimin completely despair, perhaps from this time period, the plan for the change of Xuanwumen was already in the making...
For Li Jiancheng, he completely relaxed his heart. Li Yuan had three sons in total, and due to jealousy, Li Shimin had no connection with the position of prince, and Li Yuanji had this stain on abandoning Taiyuan City, so wouldn't his position as the crown prince be as stable as Mount Tai?
In recent years, many people on the Internet have lamented for Li Jiancheng, believing that his heart is too soft, and if he is strong first, he will not end up with a tragic death at Xuanwumen.
If the situation is really as critical as we think, Li Jiancheng would have used his identity as a prince to do it, and the only reason why he didn't do it was that there was no need to do it.
Li Jiancheng has no God perspective, in his thinking, since his father Li Yuan is not ready to let Li Shimin become the prince, Li Yuanji has a stain on his body and it is impossible to be a prince, so as long as he honestly mixes these years, is he still afraid of not being able to deal with Li Shimin in the future?
If you easily attack Li Shimin, it will not only make Li Yuan deviate from himself, but also anger the Meritorious Group. Once the two sides add up to their own counterattack, in the end, it will definitely be cheaper than the third brother Li Yuanji.
Under such circumstances, Li Jiancheng had no intention of killing Li Shimin by force. On Li Shimin's side, he naturally knew this, so in such a realm, the change of Xuanwu Gate broke out.
On July 2, 626, Li Shimin launched the Xuanwumen Rebellion, killed Li Jiancheng and Li Yuanji, and forced Li Yuanfeng to make himself crown prince. Afterwards, Li Shimin also instructed his men to kill his brother Manmen.
Two months later, Li Shimin ascended the throne as emperor, and the history was called Tang Taizong.
After Li Jiancheng, the Prince of Yin, was killed, Li Shimin buried him in Guoshe Town, Chang'an District, Shaanxi. In 2005, a local farmer was expanding his backyard when he accidentally found a dilapidated tomb.
Local archaeologists rushed to the scene as soon as they heard the news, and because the tomb had been stolen many times, the experts easily entered the tomb.
After just entering the cemetery and seeing the epitaph, the expert inhaled a cool breath, which turned out to be the cemetery built by The Hidden Prince Li. After reading the epitaph, the experts even sighed one after another, "Li Shimin is really cruel."
Originally, the epitaph was only a small piece, and 55 words were written on it: Tomb of the Late Hidden King of the Tang Dynasty Wang Zhencheng Wude 9th June 4th Xue Yu Jing Shi Yue Zhen Guan Second Year Peng Zi Zheng Yue Zi Zheng Yue Thirteenth Xin Youyou Buried in Gaoyangyuan, Chang'an County, Yongzhou.
In the epitaph, it is only a brief account of Li Jiancheng's life, and the merits he made during his tenure as prince are not mentioned. The same is true in the history books, and in many Tang Dynasty historical materials, it seems that Li Jiancheng was deliberately hidden.
In fact, Li Shimin is still very concerned about his historical evaluation. He was afraid that future generations would judge him as the beast emperor who killed his brother and imprisoned his father, so during his reign, he deleted and revised the history books many times, reducing Li Jiancheng's sense of existence again and again, and even demonizing him.
"Emperor Taizong was established, fearing his posthumous name, and began to supervise the revision of the history of the country as the prime minister, so the Records of the Two Dynasties has no letters."
